A photosensitive imaging device for recording images across the entire visible
spectrum includes a set of photosensors which have a peak response around the orange
part of the spectrum, about 600 nm. The peak response is obtained by combining
responses of, in one case, photosensors associated with a filter which admits red
or infrared wavelengths and longer and photosensors associated with a filter which
admits orange wavelengths and longer. In another case, the photosensor is structured
to attenuate longer wavelengths, which, in combination with a filter which admits
orange and longer wavelengths, can simulate a peak behavior around the orange part
of the spectrum.
